Bush has been in rehab at Rancho L'Abri, a private alcohol and drug treatment facility in San Diego. He has been paying for it himself, Greene said.

Bush's alcohol troubles go back to at least 2004, when he was 18 and two months from being drafted by the Padres. He was cited for underage alcohol possession that April. Less than two weeks after the draft, Bush was arrested after a fight at a nightclub in Peoria, Ariz. He reportedly was denied entrance to the club, jumped a railing to get in anyway and bit a bouncer who tried to eject him. He pleaded guilty to misdemeanor charges and received probation and a $1,000 fine.

“This is your chance to redeem yourself, and we're all rooting for you,” Salcido told Bush on Tuesday.

Greene, the prosecutor, said Bush's punishment is “no less severe than if he was a regular guy who wasn't a professional athlete.”

“I can see where people would say he's getting off easy,” Greene said. “It's easy to say that because he is a sports figure, and that's the assumption. But he has a lot of stuff he has to do. Sometimes it's easier to do 10 days in jail and get it over with than it is to know you're going to have 240 hours of community service, 15 days of public service, a 12-hour class, 120 days in rehab. You have to be on your game for a long time, and if you screw up, you're going to go to jail for a long time.”

After being drafted No. 1 overall out of Mission Bay High, Bush received a $3.15 million signing bonus from the Padres. He never made it the majors. He failed to produce as a hitter, then was switched to pitcher in 2007, when he developed an arm injury that required Tommy John surgery.
